Description

Roquin-2 is an E3 ubiquitin ligase required for ROS-induced ubiquitination and degradation of ASK1 (Apoptosis signal-regulating kinase 1) [PMID: 24448648]. It also mediates mRNA deadenylation by recognising a conserved class of stem-loop RNA degradation motifs [PMID: 23663784]. Its structure has been revealed [PMID: 26249698].

Roquin-2 and its paralogue, Roquin-1 (Rc3h1), have been found to redundantly repress the mRNAs controlling T follicular helper cells and systemic inflammation [PMID: 23583642, PMID: 23583643].
